I have gone to settings, general on my Iphone and there is no listing for "software update". So how do I update my phone to ios 4.3 so I can download some apps that require it?
You don't the highest IOS for iphone 3G is 4.2.1.
You'll need to buy a iphone 3GS or higher
The iPhone 3G can ONLY go to iOS 4.2.1
